welcome to the club! i certainly could play with it in stock form and it would be fine. it was when i was playing defensively or returning hard serves/shots that i wanted a little more 'oomph' at the upper 3rd of the string bed. it is stable without the lead but i get a bit more power off the top of the frame now if i need it. pnuemated1 (on these boards) suggested lead running the top of the hoop which accomplished what i was looking for without impacting it's whippiness.
i tried all of the control oriented frames out there over the past year or 2 and kept coming back to the dunlop bio 300t because it just overall did everything a little better for me and i love the firm but soft feel. in my opinion it is the best light weight player's frame out there right now.
