Hi Barb,
In my opinion, I don't think either are hard. However, I do think that replating is more stressful then the mother flask. When you start out, there is nothing really in the jars to see so if one or all the jars end up contaminated it is not so bad. You can just start over. However, when you actually have months worth of protcorms in jars the reflasking part might become pretty stressful to do correctly. For example, right now, I have C. maxima that needs reflasking but because the yield count was so low, I'm a little afraid to open the jar. There are only six little portocorms in there that germinated in 5 months worth of waiting on that jar. 5 Months is a long time to wait only to end up with nothing
I say tottally go for it though if you have the patience to practice and possibly try and try again because it can be a whole lot of fun too.
