@BrianTL et al that is good to hear--I'm just going by the overwhelming number of posts I see perusing the TM thread or the photos I see in AskFC. I'm cognizant that usage has been primarily home bound for a while, and I don't pretend to have exhaustively surveyed that thread.
To me they both look about the same as far as ease of loading. The TM I'd probably just straw suck from my little grinder into the short stem. The FW I'd need to stop and pack, but I don't see that as too onerous. Ditto pocketability--I think the FW has a slight edge due to the retractable stem and its maybe a slightly thinner profile overall. Still, I think that is close to a wash--the short stem doesn't protrude from the TM near as much as I thought in pictures. If its warm and I'm wearing shorts my pockets are usually larger than what I have on jeans. If its cool enough to be in jeans there is always a chance I'll have a hoodie or jacket with larger pockets.
The main thing for me is the cooling, which also seems close (unfortunately for ease of my decision). I'll have to sleep on it. Maybe I'm mistaken and it would be easy to sell the TM for no/minimal loss and just try both.
