Testing the Rules

I've been editing/tweaking the rules for a while and playtesting as I go.  I printed the models I've designed for Horse and Musket games at 18mm scale.  They were a challenge for my printer.  Their small size tricked the printer into thinking it could go a lot faster than it should.  I manually reduced speed to less than half of my normal printing speed for larger items.

I painted some of them with spray primer craft store acrylic paints.  I'm still working on the paint scheme.  I need a way to differentiate the dismounted dragoons, irregulars, and militias from the regulars.  My ruleset does not currently have elite or inferior units, so don't have to worry about making each unit unique.  Perhaps in the future national identities and imagi-nations may develop, but for now they're going to be army red and army blue. 
My lovely wife designed a template for making hexagons with 2" between parallel sides which she cut out of printer paper on her Cricut.  I used the template on a piece of packing paper to make a field 9 rows of 8 or 9 columns of hexes.  This size results in a compact playing  surface of18"x16".  It certainly isn't pretty but it works.  I think I have a piece of 1/8 hardboard laying around somewhere that might work if painted.
I conducted a solo play test to surrender this morning.  Occasionally referencing the rules, it took me just under 45 minutes from deployment to surrender.  The surrendering player did not make an effort to salvage forces by continuing play and retreating units off of the board, choosing to surrender once defeat was inevitable.
Lessons Learned:
Distinguishing unit types from a distance is critical. Irregulars and Dragoons look similar. 
Keeping units near the center of the hex makes determining facing easier.
Keeping track of initiative points is critical.  Solved by keeping dice off board with each pip representing an iniative point. 
Keeping your general alive and relevant is very helpful.  The combat bonuses are important, but the inability to rally can end the game quickly. 
I like that each unit completes its activation before activating another.  This prevents the problem of handling combined attacks.  The only real downside is that a unit could make multiple moves worth of retreated distance. 
Things I Might Change:
Currently two units of regular infantry can form a regiment and execute identical orders as one unit.  This can make their firepower overwhelming.  It makes them seem a little overpowered.
All units get a +1 bonus when attacking militia and a +2 when melee attacking artillery. 
Currently irregulars can engage in melee.  Based on the exact period in history irregulars could represent light infantry which would engage in melee or skirmishers who would not.
Currently artillery can reposition during the battle.  For most of the 18th Century, artillery was largely immobile once the firing began. 


I've done enough tweaks to the rules that I should re-upload them soon.  I'd like to upload them as a PDF.  What is the best way to do this?
