Pad sizing True 7x3 vs Vaughn SLR4

I know this question is asked a lot but I'm having some trouble finding a Vaughn sizing. I'd love to know about goalies experiences with both pads. My FTK is about 21 5/8 to 21 3/4. From what I've found I'm at the upper end of the 34+2 in the 7x3. Is the jump to 35+2 a big difference? Currently in Warrior G3 pro 35+1.5 and my knee lands in the upper knee block and sometimes falls off. I wear them fairly loose and have skate lace toe ties. Long post but looking for any insight into sizing and/or pad feel or features.

Thanks!
