Sorry to see you missing out, as I really don't understand the statement above. The VAST majority are flying on 2.4 just fine. I have 2 Solo I use regularly myself. To make a decision based on a dozen experiences out of 1000s does not make sense to me. Like you said; "A shame to be missing out the prime summer season".
Just my opinion. YMMV..
i have two as well. i'm on 2.4, fly every week and have no worries.
