I didn't notice any difference, in terms of behaviour, between a 4 stack progressively vented to a 4 stack of full sails. That was using the "off the shelf" 4.5 foot train lines. Obviously the pull was less but both were suited to the conditions they were up in. I have the bottom train lines on the rear kite roughly 10-12mm shorter to lock up the stack on both sets.
I only have a permanent 2 stack of full sails now but it was fun.
I've heard that Alden Miller uses 3 foot train lines on his "Jimmy" stack.
Thanks. Every time I go to the shop, Mike is at work, so I haven't actually seen him there. I just saw a post that they will have their shop tent there, so at least I'll know someone's face. I remember a few other faces from last weekend, and know about half were named Mike or John, but can't remember who's who.
I believe the "professional kite" is a reference to advanced flyers who might want to "strut their stuff" on the demonstration field. Any of the teams or individual flyers who are "pro class" would love to let you fly one of their kites. I believe that team 180GO!, of which Big Mike is a member, will at the Macomb festival doing routines to music with their Revs. Don't be afraid to ask, we all love helping those with an interest to get a feel for the kite, and helping with what is needed to get out and fly. Definitely give Big Mike a call.
Polo kites are super sweet, and rather expensive. The best kite for the money, IMHO, is the Rev B-Series and if I didn't already have 13 Revs, including a full suite of B-Pros, I would be buying every B-Series I could get my hands on, including used. YMWV.
I've already signed up for IKE (Slappy). Mike and Anne's shop is where I bought the Widow NG. I was at the fly last weekend and that's what inspired the big kite purchase. I can't make WI this weekend, but will be at the Macomb one. I didn't get to try a Rev last weekend, but I'm sure that will be the next purchase. I'm hoping to get to try one out in Macomb, but not knowing anyone makes me a bit nervous. I hate to just go up to random people and ask to use their gear. This will be my first festival, so I'm not really sure what to expect. The faq says if you have a professional kite to contact them to reserve a space. Would that be limited to a Rev, or the 8' dual line? Guess the kids and I will just show up and roll with it.
