Interesting that you recognize antenna significance in your rules. But why not power too? 

A quick take  the top performers in each category tells me that beamers average 40% more effective than the little antennas, assuming average equity in power and other factors for these stations: 

Raw QSO numbers of  top 10 stations operating 6 hours ea antenna category, 

BIG (cat B)            LITTLE (cat D)
433                        281

300                        226

------                        -----
 3260                     2328

I enjoyed your contest. Next time I'll try to enter in the correct category! hi hi.

Hello Bill,

> antennas are ignored by 99% of the contest rules

please have a look in the rules from our "DL-DX RTTY Contest".

http://www.drcg.de

We don't have power categories. We have categories for

- SO1R / SOnR
- big antennas (beam) / small antennas (dipol, GP)
- 6-HOURS / 24-HOURS

A station with GP and 750W (legal power in DL) has less chance than a
station with 100W and Beam.

Since this is the case and it probably won't change, I recommend just follow the rules, enjoy your accomplishments with whatever equipment you have. QRP rigs just need a bigger antenna not an amp! If you look at it this way, then the rules aren't so "ill advised." Hi hi.
