Think twice.
You should save some cash up and buy yourself a 1.0 pied or something else lesser, lesserpastel or something else (lesserbees still cost a pretty penny, and queenbees are nice) and breed him with your 0.1 spider. She isn't far away from the 2000 gram point - she is almost ready to breed now (weight-wise).
Once the babies are hatching then you still have your 0.1 spider, some combos or spider-het 'something' and then you can buy yourself a pied or pied pair.It may take time but it will be worth your while.
Believe me... If you offered the breeder a cute, but little 0.1 pied to trade with a spider at 1400 grams - he would say no in an instant.
