I love my T-bar 36", it's so easy on flat ground but it can really need some man handling on slopes. A lot more force than pistol grips would need. If just for slopes then I would buy a pistol grip over a T-bar if I had to choose.
I used an Exmark metro 36 pistol a couple years ago and I liked it but my thumbs were raw by the end of the day even wearing gloves. I have absolutely no such issues with my T-bar but don't need to deal with many slopes.
The Toro Grandstands are suppose to be the best stand on mowers with hills.
There is an Old Blue Chair for each and every one of us, we just have to find it.
