Pro bars vs RMK steel bar bend and riser

[catfreak]

Bought a Pro back in 2011 and could never get totally comfortable on it.
I am 6'4" 280 with gear on and felt like the bars were too narrow and I felt like I was always going to fall frontwards off the sled being so hunched over.
In some of the Pro reviews some testers say the Pro bars are too agresive and standard RMK bars felt better. I see a lot of guys going to a lower bar but that would make me even more hunched over when riding. So who makes a more relaxed bar and also how tall of a riser can I go with before it screws up the ergo's??
Owned a Yamaha tank FX Nytro MTX and two M series before the Pro and both seemed more comfortable to stand on.

I got a base RMK, with the 5.25" polaris riser, it fits fine with no mod's. Im 6 foot tall, I must say I find it much better. Although Ive only ridden it a hundred miles so far this year. But I rode it last season with the stock 3" and it was a tad low I thought.

I had a 6 inch riser on a iq rmk. Found it ok but a bit low for when I was on the high side of the sled angled or angled and pointed downward. Mainly ride trees so I want the most control. I put a 8.5 on it and so far love it. Just hate the throttle, its a big reach and It takes up so much of the grip for my big hands.
