Mike,
Do you have any insight about the tonal qualities of the various wood options that Tm Alexander offers?
It is truly amazing that there are so many options available with this one man operation. Wood options including Mango, Moneypod and Koa along with 10 different sizes 9", 9 3/4", 10 1/4", 11", 11 3/4", 12 1/2", 13", 13 1/4", 14" and 15". These woods are nice mixed or book matched.
I have an amazing set of 3 Ohia wood congas buit by Tom. Only 6 of these were ever built. My set has been graced by both Tom and Matthew Smith, among 2 of the best handbuilders of congas today. (There are many additional greats too

) So I have a set of bookmatched Ohia wood congas with Matt's Crowns and bands. This is a thing of beauty.
(Statements below are only my personal opinion. In no way is this meant to discredit or discount anyone elses gear.)
These are second to none! I personally can attest that these are equal or better than my Matthew Smiths (equal), Gon Bops (depending on variety), Valje (equal), Resolution (equal), LP (much better than), Remo(much better than), Pearl(much better than), and last my Playa Azul 9 1/2" is better than my Volcano 9 3/4". Playa Azul is no longer in production but boy this is the best requinto I have ever heard. Basically Volcano is betterthan any mas produced conga: LP, Pearl, Meinel, ect.
Granted this is only my personal opinion.
Keep it fun.
