Pretty small blades on BD's shovels though.
A big blade, long shaft and D grip is what you want for maximum ease of use.  It's really one of those times where you should just just buy a good one right from the start and it'll last 10+ years with no need to "upgrade".
Voile Telepro, Mammut Allugator, Ortovox Kodiak, BCA B-52 all fit the bill but there are others.  Check out weights if you care.
More importantly, practise deep digging every year!
