With the twist grip if the bike wheels quick on you, your normal thing so to grab the bars, and it gives the bike more gas, its ruff to pushh that twist back if the bike unexpectedly wheels.
I had one on my 250r it didnt last long just my opinion, the thunb is the same way you race sleds, so I was use to it and how to flip your hand from top to bottom of the bars for left and right turns. On a hard left turn I would use my thumb, but on a hard right turn I roll my hand over the top were my forefingers catch the level.
Remember opinions are like assholes everyone has one and they all stink.
Its what you perfer, and what turns you on, or what floats your boat
