Ive only noticed a super slight, like less than 5-10 degree droop on the liger with the largest of the metal caps, i see zero droop with any of my glass caps, the dnail halo on the other hand....preheating the v2 cap is an absolute must or you'll lose 30-60 in less than 20 seconds. The 20mm can take dabs that fill up the cup to ~75% with no pooling or splashing with the right cap, mobius directional comes to mind, and it does take a LOT of draws when the temps are so low but to say the 20 can't take big dabs doesn't match up with my experiences nor many many many videos of globs and dunks......once your setup is dialed in. As far as splashing goes, the wierdeer cap has to be used with care or i get splashes all over the bucket and oils under the inserts on both the 20 and the 30.....it sucks because i strongly feel the wierdeer cap is the best chugging cap I've ever seen for the ligers and the ONLY cap aside from the storm cell 3.1 that can really make the 30mm CHUG. As far as cleaning the sic inserts, I've reposted this before and ill go ahead and do it again because you will not find an easier method......... all you need is room temp distilled water, fill the insert and soak it for like 10 mins....its like magic how dirty the water gets and how clean the sic becomes, no heat, no scrubbing, no abrasive, no iso, no muss, no fuss it simply peels away like old skin...its crazy and works great for the sic halo also. Per dab cleaning with the 20, unless you're making a huge mess, it shouldn't take more than 1 quality qtip and atlas 2 for the 30, following this i get ~100 dabs before ill do a "deep clean" with a little baking soda scrub, which also gets the sapphire inserts super clean and shiny also.
That fully wrapped 30mm coil does not fit with the standard shroud, you need a new (off sheet, custom on top of custom) part from CCA along with the coil from Augusthaus. I still strongly caution anyone trying to go the Augusthaus coil route as the design of the liger itself mitigates the design of the wrapped coil with its huge nail mass, it would be of more use with a low mass setup like the halos or if it was still 2013 and quartz nail were still the rage, something that doesn't already have a huge amount of intermediate heating mass and needs the heat physically brought further up the dish, which if its sic, will have amazing thermal transfer already.
Not trying to knock anyone or hurt anyones feels or attack their methods nor am i saying anyone is "wrong", this info is all my anecdotal experience and knowledge gleaned from personally applied research all geared towards reaching the tastiest chugs we can get, efficiently as possible.
