----------------------------------
XL2 has a round aluminum alloy front crossbeam with strut (seagull or 
pelican striker) parallel with the forestay.
Most of the cats I have seen with round front crossbeams and struts have 
had them aligned thus.
Many cats with aluminum alloy front crossbeams do not need a strut. I 
think this may be the case with XL2, that is I could delete the strut or 
reduce the wall thickness of the beam.
