Reo grand or provari...durability or functionality, bottom fed or cartos, box or tube, apples or oranges. They are both arguably at the top of their respective genres (if only the reo was VV I think we could end that argument) and neither of them are going to pocket fire on ya. Now talk to me again when someone makes a bottom feeder that has the same feature list as the provari with the durability of the reo and we'll see what I have to say (yeah that's a hint to all you potential moders......get to work!)
