Hi
@deadlytoaster, exciting you got a Hopper, I'm happy it's working out well for you so far!
How about GHB2 batteries? I get about 1.5 bowls per charge. Do the GHB2 batteries improve much?
I have 1 GHB1 battery and quite a few GHB2s. I find the GHB2s last significantly longer than my GHB1, generally getting 3-4 bowls from them, depending on the Will of the Gods. Often I find that after the low battery indicator (red flashing leds) turning it off and back on again I can get several more hits, sometimes a lot more, before it's actually dead.
So yes, I'd recommend some GHB2s sometime, when you can invest. Not an enormous difference, but it will help. If your batteries were shot (which it doesn't sound like they are), then they could also improve performance, but probably not in your case, as it's already performing very well. Buy the batteries when you get a PFE.
I haven't used a hydrotube, nor have I seen others here use them with a grasshopper, but I'm sure it would work well. I don't know what size the joint of a hydrotube is, but bear in mind that the PFE is only 14mm, so you may need to use an adapter.
@nonbeliever, that is all fantastic news. Long may it continue!
