Hi Patriot. I'm sure you will get a lot of advice on your question, but I am in the minority that prefers the thumb throttle. On my Vision Recumbent the brake and shifters (Shimano Deore) are combined, with a thumb lever to shift down, and an index finger lever to trip for up shifts. I suppose there are other style thumb shifters also. Anyway, when mounting the throttle ahead of all this, I could not get it on the handle far enough to allow full room for the grip, so I added about an inch to the handlebar (using two compression things made for bar end mirrors). It all works great and I am happy with it. The Vision has under seat steering and the bars point to the rear of the bike. The only drawback is I have to release the throttle to shift down when going up a hill. On my known routes, I normally set up a little higher geared at the start and shift the front down when the going gets tough.
