The wood looks a lot better with a generous amount of tung oil. I did 7 coats (first two coats were 50/50 tung oil and mineral spirits and the remaining coats were pure tung oil). I used 600 grit sand paper to rub in the tung oil and waited 24 hours between coats. It improved the look by quite a bit.
But I agree, mango wood isn't an ideal choice but I guess it's readily available where MonkeyNutz lives. I would have preferred walnut or maple. I might take a wood turning class this summer so who knows, maybe I'll try to make some myself.
if you do, HMU :P
Might need some woodies for a stratoKOSSter in the future.
