For those interested, I'd like to share my (for now) final version of my BRM V1 modifications. The performance is really good. The wing flies more forward in the window and generates more of its own apparent wind.
The changes:- BRM bridle mod
- Inclusion of a yoke for the B-lines
- Center 4 B-lines connected to the A-line attachment point
- "Wing-style" bar, which creates more of a 'hang' feeling
- Shorter bar as well
- Center 4 A-lines wrapped with Velcro
- Direct leash connection to the A-lines (and the 4 B-lines)
- Traleaze: Leash and trapeze line combined into one (with swivel & QR)
- O-ring as trapeze connector
- Silicone tube used as a stiffener
The advantages (compared to OG V1)- More forward flying
- More apparent wind generated
- 'snaps back' more easy after pump
- Much less nervous/twitchy
- Stays in the 'happy place' more easily
- Higher upper wind speed limit by characteristics alone (and even more due to the tralease)
- Very easy A4 stow
- More of a 'hang' feeling at the bar (think Duotone Slick vs Unit)
- Pressure relief, as the leash is the same length as arm length (no line stretch), resulting in less load when both hooked and unhooked
- O-ring hooks in smoothly and also releases easily when needed
This is on my 4.0. I did a similar mod on my 2.9, but with the 'V2-style' bar. I prefer this setup.
