@Old_Skeet, I hold AOFAX in taxable and in my Roth, and since I use only my taxable account for modest withdrawals, I am not concerned too much about the cap gains, will just take it as ordinary income and leaves more cash in account :). Besides, half of my taxable account is in muni bond. AOFAX has taken a big hit over the last 2 months, but holding, I like the manager and everything is getting hit.
Regarding the two funds you mentioned, I always like Gabelli, but I am sure he will retire soon, and although it has a large management team, I get the impression he is the master of his universe. It has been around a while, and have heard about it for
years, but never sought to buy it since I liked others I had better. Regarding the Ivy fund, used to own its tech fund, but had to sell it when I moved from ML to Fido, they did not carry their funds at the time, bought PRGTX to replace it. I see they do sell them now, with IGWAX load free and ntf. Morningstar gives it only one star based on its fees, not taking into account it is sold some places without the high fees. That fund looks like it would be a nice complement to aofax, with larger amount of microcap and no mid cap, but it sure can be volatile, but with your diversification, it most likely would not bother you too much :)
