Use the bolt-on option shown in the planes (parts are even provided... I recently built one for our club.) You'll love the convenience of the nylon bolts, and the absence of the mess of dealing with the gummy rubber bands after flying.

If you have previous experience, yeah, go with bolts....if on the other hand your "Pilot In Command" time is pretty short, rb's might be wise 'cuz those landing can be tuff on the fuse when bolts are present

If you've got enough rubber bands onto keep the wing from shifting in flight... it won't allow movement any quicker than the dual nylon bolts.

You can improve the wing release with the bolts in event of a crash... fill the space between the ut plate and the bottom of the wing with soft balsa (remember the aileron torque rods...) and cap that with 1/32 aircraft ply, in a manner to have the ply rest flush with the bottom of the wing with it properly bolted down. In event of a crash...the ply will act as a knife and cut the bolts. In normal flight, its dull enough to not even wear a groove in the bolts if the wing is tightened properly.

NOTHING yu do will prevent all crash damage though. Build it to fly... not to crash.

Be sure to take the above advice about making the mateing surface between the wing and fuselage flush. You should also reduce the size of the nylon bolts. Use 8-32 as maximum (you can really get by safely with 6-32 nylong) if you plane weighs less than 8 pounds. The 1/4-20's that usually come with kits is much to large and strong. The structure will break before the bolts will. I use only 10-32's on my 15 to 20 pound big birds and have never had a failure other than when I have had a case of dumb thumbs and then the bolts broke before structure just as they should.
