You could even try progressing to L Pullups. Trust me, being able to do 20 strict L Pullups is far more impressive than doing 5 neutral grip chins w/ 70 lbs.
On the other day, you could go ahead and crank out sets of 5 with a neutral grip, swinging a couple plates off your waist. Just keep the form reasonable, and don't get too emotional and hurt your wrist/shoulder/elbows.
That's my current chinning routine. Mondays I do heavy weighted chins with fat gripz (chest to bar), Thursdays I do three sets of L Pullups to failure.
