Quick question of board choice

Hi All,
I have just officially joined the site...although I have been perusing through it for about a month or so.
I have a quick question...
I currently surf a beach break which is not too bad consistency wise. My question, I was given a 6.8 x 20.5 x 2 5/8 "shortboard". I have been mainly surfing on a mates 7.6 Mal which has been a blast. I am able to catch waves consistently and able able to ride the open wave (only been in the water +/- 20 hours since i started) so feel that my progress has been "steady'.
My question is, should i try sell this board and get a fun board (although on bigger days i struggled getting out on my mate's Mal) or do you think that the length, width etc is sufficient for me to continue my progression? I am 5.10 and about 80 kgs...paddling fitness is improving but just don't want to be left too frustrated surfing on my board....i want to still achieve a "high" wave count and hope this board will not be too difficult to paddle and that it's stable enough for me to "pop" up. The beach break can get hollow and this "shortboard' seems to "fit" the wave better...or so i have been told.
I would appreciate enough advice.
Thanks!!
ps: I am super stoked to be "surfing' at nearly 36 years of age!!!
