I been where you are now. I have a GoLite Hex3 and I sewed netting all the way around the base of it with velcro. I used a 16" wide strip of noseeum and simply tucked it under the floor or tyvek ground sheet, depending on what I was using at the time.
I've since removed the whole netting business because I came to the conclusion that the Hex3 was a winter tent. It excels in every way for winter use but, was really hot cave in summer and bug were problematic. In winter bugs aren't a problem so no need for netting.
I bought Big Agnes Seedhouse SL3 for summer as the inner tent is all net and we simply keep the fly at ready, just in case of a shower. It's really a large 2 person tent. BPL did a review at ... http://www.backpackinglight.com/cgi-bin/backpackinglight/big_agnes_seedhouse_sl3_tent_review.html
