What Size Kettlebell To Start?

I'm planning to buy a kettlebell but I am wondering which size would be best for me, the 35lb or 53lb size. I am 6'2 240lbs and worry that the 35lb kettlebell would not be enough because I usually use dumbbells that are heavier than that during my typical workouts.

On the other hand, I would hate to let my pride overload my workout and end up starting with a KB that's too heavy and sacrifice good form.

Any suggestions from experienced kettlebell users would be appreciated!
