First off, seeing as you are in Ohio you might want to check out some of the control line clubs. I don't know where West Chester is in relation to Clevland but there are a couple of clubs in that area. Check out their web site to get started in that area:

Brodak is a good source of kits,engines, parts, etc etc. Great web site and John is now publishing a magazine called Control Line World that is very good. Sells some ARF and ARC kits that may appeal and might fit your engines. John Brodak also hosts a large control line Flyin each year. Gets good coverage in Flying Models and in various other locations around the net.

A good trainer for your .25 size Norvel might be the Top Flight Flight Streak ARF available from Tower hobbies. Check out their listing for this kit and you will see some recommendations for various things.

and finally, not to knock this forum but there are other control line specific forums around.

http://controlline.org.uk/phpBB2/index.php of the Barton club in the UK
http://www.clstunt.com/htdocs/dc/dcboard.php probably one of the oldest control line forums
and some good reading, the Australian Control Line Newsletter:

Of course I may be preaching to the choir and you may already know of or have run across much of that info before.
Control line flying is addictive - not better nor not as good as RC, but different. It is fun, a challenge and will add another dimension to your hobby, spice of life and all that.
cheers, Graham
