@ma0u here are some of my thoughts.
Lets start with the nail.
Domeless is nice because no glass dome is being used that could break if dropped.
A dome with a quartz or titanium nail is also good.
Dome vs domeless is honestly preference. I still use both but I would say I use domeless more.
If you are worried about putting titanium on glass you don't have too much to worry about. I have never cracked any of my glass pieces. Once the titanium nail just slightly starts glowing red in one spot I stop heating and let it cool for a few seconds and then use it. You can also throw a glass on glass adapter over your male joint on the rig to protect the male joint.
My preference for flavor:
1) ceramic
2) titanium
3) quartz/glass
*note: if you season a new quartz nail 3-5 times with some bad oil before using it I would say quartz is on par with titanium.
My preference for durability:
1) titanium
2) quartz/ceramic
3) glass
Quartz, ceramic, and glass nails will all crack eventually. So don't pay a lot for them.
eBay has quartz and ceramic nails for under $20. Here is a seller from California that I really like.

However for titanium you need to be a little more self conscious from where you buy. Yeah you can get grade 2 titanium for cheap from china but I don't recommend it. Stick with brand name like highly educated or Silika or ti power or dab essentials or vapenwiser. If you have a budget go with new-vape.com or look at the seller of new-vape products on eBay.
Search this on eBay to get that sellers listings of the new-vape titanium nails.
seller:custom9001
Their titanium is cheaper than brand name because they are a new name company but their titanium is very pure and it comes with a test certificate showing its purity
I have a mix of titanium, ceramic, and quartz nails. I use all three regularly so if you can afford all three (about $15 for quartz, $18 for ceramic, and $30-$40 for a new-vape titanium nail) you should get them all
As far as a torch goes the GT8000 is great but a little expensive. About twice the price as my Newport cigar torch I got on eBay for $30 and it is great. No problems with it so far and I've had it for about a year now.
You can just search Newport torch on eBay and a bunch of colors will come up. Get one that looks like this though. It is the one I have and I'm very happy with it.

As far as glass goes anything with 2 or more percs will result in flavor loss but cooler vapor. It is all personal preference. For concentrates I usually stick with one perc rigs but I do own a few double perc rigs that I use all the time. I would get one single perc rig and one double so you have both
Out of the GB-197 and Kathy's big seller I would go with Kathy's because it is clear. I'm not a big fan of color in my glass and that's why lol. Both are good Larger dab rigs though. These both would be great for vapor too if you have a vaporizer.
I would pick the double barrel recycler JH012 over the GB-194 any day. I don't have the 194 yet, should be here this week, so I am a little biased but I can tell you I use my JH012 everyday and when my friends are over that's the one that gets used the most.
Also notice the 194 is a female joint and will need an adapter to use any female joint nails you buy.
I wouldn't recommend using ice with concentrates. Don't quote me on this but I think that the ice would cool and harden the concentrate vapor which would cause the vapor to get stuck to the ice and therefore would result in some lost vapor and sticky ice cubes lol
I was told by a few pros to even use warm water in your rig because it allows the vapor to travel through the water more easily thus resulting in more vapor in your lungs
but cooler vapor is easier to handle so if that's what you need then throw ice in that rig!!
Don't get me wrong I love ice when I use my volcano or solo but I stay clear of ice with concentrates. Just my preference.
Any of the rigs posted here or in my previous post for you will not have hardly any drag at all so your lungs will be good!
STAY CLEAR OF THIS ONE

The quality is absolute crap and I know it is cheap but compared to others this one will disappoint.
So now for the mini layer cake and the mini recycler from Kathy I would go with the mini cake:

I use the mini cake all the time with my 10mm new-vape domeless nail. my friend actually liked it so much he orded that same setup yesterday lol. However, when I owned that mini recycler it never got used. Hitman originally designed the mini cake so that should tell you something
Hitman definitely didn't design that mini recycler.
Well that's my 2 cents. Good luck!
