Stu and mvapes, I've tried both an HT and ELB with the Q. I've got posts way back with pics, but don't bother you guys already know the ways how you'd do both, and neither worked well. A few days ago though there was discussion doing this with an adapter converted to a bowl; this was/is the only way I see working (plus possibly substituting an ELB) but until this week I couldn't find a female/female adapter that properly fit down inside on the Q joint. I've bought one of those and will try the same experiments again. I don't expect to get Cloud performance, but it might make for a very cool Q mod.
Next week I'm on the table
with my new cutter friend
, I'll have plenty of recovery time to dabble. I'll post back what I find.
