Hey guys, will this work?

Refresh your duty cycle only when it need to, unless you'll have problem.

try something like

START:
        ADCIN 6, CSET 'READ VALUE OF CURRENT SET POT
        ADCIN 4, CSEN   'READ VALUE OF CURRENT SENCE
        IF CSEN > CSET Then LET DUTY = DUTY - 1
        IF CSEN < CSET THEN LET DUTY = DUTY + 1
        if DUTY != OldDuty then
            OldDuty = Duty
            GOSUB NewDuty 
            ENDIF               
        GOTO Start

NewDuty:
        TMR2IF = 0
        while !TMR2IF : wend       ; let current cycle complete
        CCP1CON = 0  
        CCPR1L = Duty >>2   
        CCP1CON.5 = Duty.1
        CCP1CON.4 = Duty.0
        RETURN

You'll probably need to allow an error margin in your IF-THEN, remember you have a 7 bits or so PWM resolution but 10Bit ADC results. Reduce your ADC resolution to 8 bit may help.

You also want to make sure you don't overflow the Duty value...

Seeing your schematic would be nice.
