I make quite a few of both.. they are my top selling style pens... the cigar is a decidedly larger pen and some people really like the size, especially if they have the beginnings of arthritis or their hands cramp from writing with a smaller pen... I buy all my cigar kits from either Arizona Silhouette or Woodturningz... you can't beat the pricing from them... it uses a 10mm bit for both the top and bottom.. because of the size you can modify the design more than a smaller pen.. but I make them in the traditional style.. have not found bead and curves sell as well for me
The Perfect Fit I would classify somewhere in size between a Double Twist Euro and the Cigar, but closer to the Euro.. it is turned on a Berea B mandrel and as noted requires two different drill bits.. but as you go along in penturning you will be acquiring a whole lot of bits anyway... LOL I recently purchased a set of bits to 1/2" in 1/64" increments from Harbor Freight that fits the bill for those sizes I would need anyway... in the long run it was cheaper.. these were TN coated bits and I think the cost was a whopping $30..
The Perfect Fit does not lend itself to much experimentation, but there are things you can try (as I am) to make them unique... I personally like the size of the PF, it fits my hand nicely and most people who pick one up like it immediately... in fact they also seem to like the look better than the Euro.. I generally make them in lots of 6-10 in the same wood.. that way I can sell pen and pencil sets of the same wood if the customer wants, by only changing out the ink refil for a $2 pencil refil.. this makes the PF a real economical system for pen and pencil sets.. I generally try to make these pens in my better woods because they look very elegant and I can command a better price for a nice looking pen... another thing I tend to do is replace the ink refil with a gel ink refil, it really makes the pen write better and is a real sale getter... when a customer tries out a pen, if it writes smoothly and comfortably, they are more likely to buy it...
Give them a try, I think you will be pleasantly surprised...
