Drummers, specially the beginners or intermediates use 14" hats and 20" ride because its the mid-range size. Ibig sabihin, hindi sya risky. Sometimes, its not the size, its the weight.
Masarap yung ride na may magandang cut ang bell, yun bang mabigat na ride like the Z's or Z3's, Ping's and K Custom Ride. Tapos ipartner mo sya sa hats na may magandang cut at chick definition like the 12 or 13 ichers. Vic mercado uses A Special Recording hats 12" and K Custom Ride 22", I think... Kaya maganda ang projection at cut ng hats and ride nia.
And depende yan sa genre or sa taste mo... For example You would not use a ride that is lacking on bell and a hats that is very washy if you were a gospel or rnb drummer right?
