I can't even begin to imagine stringing out 200' lines... heck we're happy if theres that much clear area to work in!
The topic made me think of something that Tak and I go back and forth on all the time... are there some kites you guys won't fly on particular line lengths? He plays with the indoor on 75's outside when theres no wind, I fly the shockwave on 65' lines, and we both think each other is crazy. But the more I think about what it would look like to have 200' lines, I keep thinking a Blast would be very fitting on the end of them!
I don't think I would ever fly my rev indoor on anything longer than 30, maybe 60' if it is a really big indoor venue. My rev indoor takes enough abuse from me as it is without me taking it outdoors XD
I also don't think I would ever fly a blast 4-8 on my 5 or 8 foot line sets...... I just don't think it would really fit.
