With those current modification riggings you can go into bigger wind than you ever thought was appropriate. Remember the whole point of all the rigging front and back is to spread the dynamic forces and increase the responsiveness. Since there's no oversteer wiggle possible in the bridle anymore you'll feel a strong surge of wind (across the center of the window for instance), easy to fly off to the side or up-top riding out a sudden unexpected gust. I give ground, but friends stand lead footed, it's been proven plenty strong, rest easy.
Make sure you have the bridle installed properly, when it's perfect and only then.... "paint" the knots with nail polish. Let this polish dry overnight, not just to your touch with a finger tip.
Tune the bridle with the kite inverted, ideally adjusting the attachment points on the bridle as opposed to the handles (the bottoms). That way when you switch from stock to French bridle it's tuned correctly either way. The kite needs to back-up inverted from the leading edge resting on the ground (in low wind you may need to walk backwards also).
Stock out of the packaging the FB is tuned to 15 inch no-snag handles with Barresi's leader knots. Myself I use longer handles and WAY longer leaders.
If it doesn't fly faster in forward and still hold all the reverse, if it doesn't feel more responsive, then give me a call and I'll coach you though some testing. We'd start with the usual questions. Lines even, laid out cleanly, affixed to the handles which perfectly align in your hands when jerked back tight from a well placed stake or fence post?
I expect you to love this rig like a first borne child, but it might not be the first few flights <LOL!>
