Extra bracing

I have just started to assemble my wings on my all wood aircraft. There
is a box spar in the front and a 3/4" thick spar in the back. Although
this will no dought hold together, it only calls for 1 diagnal brace on
each wing. I glued temperary
diagnal braces on the inside to hold while I start to cover. This has
added an extreme amount of strength. Now that I've led to the big
question. Since this will add only 1lbs to the airframe, does anyone
think it would be a good idea to keep the extra bracing? Or make the
frame too stiff?
