If everyone else has gone to 2.4 at your field that should mean even less problems for you on 72MHz, since you'll worry even less about someone on the same FM freq. Will the club not allow FM AT ALL? Even though the new technology is superior for many reasons, doesn't mean that the older technology is obsolete.
You're always welcome at our field with your 72MHz radio. It's a bit of drive for every day flying, but come on out when you can stay all day and justify the drive (Hendersonville to Hickory, about an hour and 15 minutes, up I-26 to I-40 East)
