Probably going to place orders for the Fan and Pipe this weekend.

Question for you experienced folks:

I've already settled on the Dynamax tractor fan. RUnway is 400' long paved, so there's plenty of room for her to take off.

However, I've not yet selected a pipe. Honestly, the only options I've been able to track down are either the System II pipe from JMP (their page says they're out of stock however) [EDIT : Just spoke with JMP, they claim the pipes will be available again by the first of the year. I can certainly wait that long, but should I? Anyone have opinion/experience to suggest that JMP will (or won't) be good to their word on that? Is the pipe good enough to wait that long for it? Etc] or the pre-tuned pipe Bob offers on his website.

Does anyone have a source/suggestion?

My criteria are:

1) Top speed is not hugely important. I'm quite certain this thing will go plenty fast enough for my liking, so squeezing a few extra MPH out of it isn't an issue.
2) I'd prefer a muffled pipe, simply for personal reasons. I like quieter aircraft. It's not a requirement by the club or field or anything, just personal taste. I understand a muffled pipe will probably cost me 1-2k RPM...not a hge issue (see 1 above)
3) Price...Bob's pipe goes for $119, the JMP System II pipes for $180...so, I'm thinking the $150-$200 range.

I call upon the power of RCU.
