Please critique my cutting plan

For some background, I'm 36 y.o. 6'6", 255, been lifting for about a
year. I haven't had a body fat measurement, but I'm pretty happy with
the muscle mass I've built up so far -- not huge but people definitely
notice I've gotten bigger. My main goal from now till summer is cutting.
With that goal in mind, I'd appreciate comments on my diet and exercise
plan.

Daily diet: 3000 cal: 260 g protein/340 g carb/67 g fat
Mostly fish, chicken, yogurt, milk, brown rice, whole grain breads,
oatmeal, fruits/veggies, flax & olive oils, whey after workout, casein
before bed, 6-8 small meals per day.

Exercise Plan

Monday: Upper body weight training, 3 working sets of 8-12 each, 1-3
minutes rest b/t sets:
- barbell rows
- bench press
- close-grip pulldown
- military press
- shrugs
- incline bench

Tues: High-intensity aerobics class (1 hr) -- kickboxing moves, football
runs, bodyweight squats & lunges, tons of ab work, push ups, dumbell
work, etc.

Wed: 60 min stationary bike, high-intensity (FWIW, I go 20 miles and
burn ~800 cal according to the bike computer; HR 140-150 for most of it
- resting HR currently ~64).

Thurs: Aerobics again

Fri: OFF

Sat: Lower body weight training, same parameters as above
- full squat
- SLDL
- barbell heel raises (calf)
- Ab stuff (crunches, leg lifts, etc.)
- I've been wanting to add DL's on this day but usually the leg work
wipes me out.

Sun: OFF



Thanks in advance!
