Okay, let's be clear on what we're going for. As I see it, we want as granular results as possible, using a single roll, a single, elegant (hopefully even fairly simple) mechanic, and the minimum possible number of reference tables consistent with the granularity we're going for.
I am not going for simple, if I wanted that I would stick with the combat tables as presented in the HARP Fantasy book, as they do work well for what they were intended to do. I prefer and some others have indicated they prefer a more detailed (or granular) route. Many people prefer (as my players and I do) the two roll method, one for hits the other for crits.
I agree with most of what you said GoF. I am going to make this as simple as I can but still give more varied and balanced results. But like I said there will be options to go the further route (e.g. armor vrs attack type mods) if one so prefers.
I have an idea for a "level of complexity" table to show how much more complex these rules will be the more options one uses. Just a basic idea for now and I am not sure if I will put that in there.
My tables are based a great deal on existing ICE combat tables (RM and HARP) so as to keep some fluidity and familiarity between them.
Just to give you an idea:
Currently my tables resemble the H&S tables as the columns are separated by attack sizes (Tiny, small, med, etc..) and the current max results are at 150.
Where they differ is I use the max damage results in the HARP Fantasy combat tables per weapon sizes, at a result of "120" on the tables. So they are balanced with the current HARP combat guidelines only you don't need the weapon size mods on each chart.
A result of "120" on the tables I am developing is a max damage line but the tables go up to 150 for now. That line can be crossed though I haven't decided on to use the HARP rule of a natural die roll of 99 or 100 to break that or some other maybe easier way to break max method (any suggestions?).
Currently the crits on a result of "120" will indicate the same exact results as in the HARP Fantasy book per weapon type and size (HARP Fantasy; 80 was tiny, 90 was Small, etc..).
For example: In HARP fantasy a dagger's max damage result (25 hits) is the same result at 120 on my tables. The crits will differ a little though and I can tell you that if the crit result in HARP fantasy didn't kill at it's max damage (i.e. 80, 90, etc..) then it will not kill at "120" on my tables.
I am also making conditions so even in a 2 roll method they will not kill, unless certain conditions are met (i.e. power strike, charging, etc...) This is part of my plan with being able to break "120".
Also I am using only crit levels "A" to "E" with a # (1,2, or a 3) next to it. For one to reference the simple crit table (like H&S) and also for those to use the RM crit tables if they so prefer. One idea I am toying with is the #'s next to the crit letter (A1, A2, etc..) will indicate a mod to the actual crit roll on the two roll method.
This system I am developing is essentially a combinational rewrite of the other optional tables out there for HARP. Though I have developed something like this before when I didn't have access to any RPG stuff (also didn't know about the H&S or HARP to RM combat tables).

P.S. I am not sure if "combinational" is actually a word but it fit so well...lol
