ok, all good suggestions.
Let me clarify my situation further.
I did my NAR cert in March 1991 (in fact I was the first HPR consumer certified by NAR), then got confirmed in Tripoli in June of that year. Bought a Magnum and a 54mm casing from Ron Schultz at Danville in 1991, but never used them and sold them in '97. Basically, I got HPR out of my system early.
I have three L2-capable HP rockets, all built in 1991. The Caliber (never flown), an EZI-65 (flown about 30 times), and the MegaAlpha (9 flights), which is essentially a stretched Minie-Magg. All were built before the advent of dual-deploy.
I want to do a cheap'n'dirty L2; motor deployment only. Since my hardware is 38mm, J350 seems like the safe choice (I'll have to beg a longer casing). Don't want to build a new rocket, don't want to convert any of the existing ones to dual-deploy. Lilly, GA is the field of preference, and Leonard has just lowered the max altitude there to 5000'.
I built the MegaAlpha to fly on up to K motors, but I've only flown it on I211, and see no reason to use anything else. Plus, it has sentimental value, and I've already almost lost it once on an I211, and reefing the chute is problematic because it already comes down pretty hard on a 50" chute and the hard pointy Alpha fins.
The EZI-65 should be ok; its payload compartment has been stretched, so ballast should be easy, but I wonder about the thin fins on a J350 boost (it *has* flown under H238 and I211)
So the Caliber is my current choice, I'll just have to use some ballast.
Ideally, I'd just fly the MegaAlpha, go to about 3000' and be done with it.
Maybe if the wind is right that's what I'll go with anyway.
