Digital BW, The Print

I'm about to order a Wacom Intuos tablet, and am equivocating about the 
preferred size.  I have a Graphire 4 x 5 and want to upgrade.  There is a 
"show special", so I get a few bucks off the regular price.

I'll mainly be using it to draw mask outlines, as well as PS retouching, 
and wonder if the 4 x 5 would suffice, or should I go for the 6 x 8, for an 
extra $100.  I'm also willing to try to learn to use the tablet 
exclusively, rather than the mouse.

All opinions and reasoning welcome!

Thanks...... Jack Winberg
