I have both and they are both good. Both have good low end. The lines on the BRM are shorter than the PT.Skin and not as fine.
Both the D handle and bar on the BRM are about half the size of the PT.Skin bar.

The BRM locks in solid with the wind, no wriggling around at all in the wind.

Both of them can be pumped, but the BRM seems to lock onto the wind a little better.

Both are made of light material and pack into a small package.

I have not used the PT.Skin since I got the BRM.

super good info, thank you!! what size of the L1 do you have and what is the wind range? I’m 100kg myself.

Greg asked me over a year ago what size I would like and I asked for something over 7m. I think he out did himself with the BRM L1 7.5m.
Completely consistent with the designs he has always pursued. I still have a 2014/2015 17m strutliess Cloud and still kite foil it sub 10 knots.
